VINCENS DEMOUNTABLE DOOR HINGE 2Sheets-Shut 2 Filed Oct. 15, 1962 I This invention relates to? cabinetsof which the frame structure consists of metalframes made of sections ofthe i United States Patent:()

type described and illustrated in the US. Patent No.

' The aforesaid patent also contemplates the possibility of fittingdoors on a rack of this character for converting same into a cabinet,and'to this 'end the rack receives at the four'corners of .its frontface fittings constituting the i female elements of door-hinges whichare adapted to receive the pins of the door-hinges. i 7

However, the doors thus mounted are objectionable inthat in their closedposition they project from the front face of the cabinet and showrelatively large Clearances along their outer edges, thusperrnitting theingress of dust into the cabinet. i I a It is the essential object ofthe invention to provide an improved door mounting arrangement forcollapsible metal cabinet according to the aforesaid patent, 'which ischaracterized in that two 'strips carrying the door hinge plates aresecured respectively on the upper portion and on the lower portion ofthe front frame of the cabi- "net, and act as fillistered casings tothese doors.

Other features of the door mountingarrangement ac- FEGURE 4, is ahorizontal section taken upon the line IV1V of FIG. 3; q

To facilitate the understanding of the present invention,-

only the upper strip of the cabinet will be described hereinafter, butit is clear that the lower strip is of similar design.

door hinges, so as to constitute the element of a fillistered casing forthes e doors. i

As shown in the figures, the hinge of each door is shifted outwardlyfrom the main plane of the relevant door to permit an angular movementof about 270 of the door; thus, in the fullyopen position each door canengage the corresponding side post of the cabinet an free its front facecompletely. The 'lower flange of strip 1 has a hole 32 formed inthe'vicinit-y of its outer edge and'overlying this hole is a weldedinverted cup 8 constituting the female element of the door hinge. 7 Eachdoor has;secured along its vertical outer'edge a channel section 9vhaving a half-round bottom, this 'section protruding from the frontface of the cabinet by a length correspondingsubstantially to thethickness of the side posts of the cabinet.

Fitted in the upper end of section 9 is a bushing 1 formed with a topflange 11 bearing on the upper end of this section. This bushing 10 isalso formed with an axial bore 12 adapted to receive the male element 13of the door hinge. This male element has a lower extension in the formof a rod 14 bent at right angles, the

outer; horizontal portion 15 ofthis rod extending rearwardlyandcooperating with a lock plate 16 secured on the door liner; to this end,this lock plate 16 has a U- shaped aperture formed therein (Fl-G. 5),the vertical base 17 of hisaperture being narrow enough to prevent the.sliding engagement of said bent portion 15 therein, and having a lengthcorresponding to the stroke of the male element 13 from its retractedposition to its engaged position in the female element 8; the twohorizontal portions 19 of this aperture form therebetween a locking lug26 the purpose of which will be explained presently; on the other hand,the width of eachho rizontal portion 19 permitsthe free sliding movementof rod 15.

The lower flange 6 of strip 1 is provided as usual with a door stop 22and formed with notches 21 adapted to be engaged by the doorespagnolette bolt.

The free edge ofthe lower flange 6 of strip 1 is also providedpreferably with a plurality of notches 18 to facilitate the removal ofthis strip if desired, by inserting therein a screwdriver or othersimilar tool acting as a lever. t i

.The lower strip is exactly similar to the upper strip,

' except that it is mounted upside down, that vis, with its The strip 1consists essentiallyof a channel section of a length equal to the widthof the cabinet and of a width permitting the straddling of the uppercross member 5 of the front frame of the cabinet.

Theupper flange 2 of this strip haspunched lugs 3 formed in thevicinityof its free edge for snappily engaging the free edge of theupper flange 4 of said cross member 5; the free edge 31 of the lowerflange 6 of strip 1 is bent upwards at right angles to'its plane so asto engage the free edge ofthe lower flange 7 of said cross member 5;thus, the strip 1 is locked on cross member 5 by the lugs ,3 and thebent portion of its lower flange, as shown in FIG. 3.

T 0 permit the engagement offlthe lower flange 6 of this strip under thecross member 5, the former is formed with notches 6a at either end,thewidth of each notch corresponding substantially to the thickness ofthe vertical side posts of the front frame of the cabinet.

When the strip 1 is anchored on the cross member 5 it projects from thecabinet front face by a distance corresponding substantially to thethickness of the doors and lower flange identical wtih the upper flangeof the upper strip; preferably, the male element 23 of the lower doorhinge is molded integrally with the lower bushing 24; otherwise, thisbushing 24 is exactly similar to the upper bushing 16. n

Small plates 26 are secured on the ends of each strip 1 for occludingthe section thereof which protrudes from the front face of the cabinet.

' The method of assembling this structure is clearly shown in theexploded view of FIG. 2.

Firstly, the upper strip 1 is fitted in position by anchoring itslower'flange 6 on the lower flange of the upper cross member 5 of thecabinet, then this upper strip 1 is'pushed home backwards until thepunched lugs 3 on its upper flange are snapped in position for lockingengagement with the free orinner edge of the upper flange 4 grease? 20closed, thus lockinglsaid element 23 in its operative 1 impart a morepleasant appearance to, the cabinet, but in this case, it is'diificultto line also the channel members 24 are preferably made by. mold- 3. Ina collapsible metal cabinet having a frame struc ture comprising twoframes consisting of vertical upright sections and'horizontal transversesections assembled by resilient mutual engagement and doors havingsection 9 of the doors'as described hereinabove and illustrated in thedrawings.

'TAccordingto another feature characterizing this invention, thesechannel'members 9 may be covered by asuit- I ably' shaped beadingadapted to conceal the vertical edge of the door lining. I

To this end, this beading 27 has a cross-sectional configurationcorresponding substantially-to that of channel elements alongtheir'edges and mounted by means of hinge pintl'es on the corners ofthefront frame, and lateral and bottom panels, a pair of get-up stripssecured respectively on the upperand lower transverse sections of thefront frame,.each get-up strip consisting of a U-sectioned element of alength corresponding to the frame width, of a height permitting ofstraddling said transverse sections and of a depth exceeding the framedepth by a distance corresponding to the thickness of the door and theirhinge pintles, one of the Wings of said element' having punched thereininthe vicinity of its free edge projections capable of engagingelastically from behind said free edge the member 9, and its outerflange is bent twice at right V angles inwardly, its free edge 28 beingadapted to engage a vertical slot 29 formed to this end in the door.

. FIGURE 6 illustrates the fitting of this beading, which is simplythreaded on the aforesaidichannel member 9.

Although the present invention has been described in conjunction with apreferred embodiment, it is to be understood that modifications andvariations may be resorted to without departing from the spirit andscope of the invention, asthose skilled in the art will readilyunderstand. Such modifications and variations are considered to bewithin the purview and scope of the invention. and
